We often get asked can traditional timber sash windows be double glazed? The simple answer to this is yes! Many people are unaware that it is perfectly possible to double glaze traditional timber windows. In fact, the majority of new timber windows that we manufacture are double glazed as standard.
Although double glazing existed earlier, UK households didn’t start to install double glazed windows until the 1970s and 1980s. This means that houses with original timber windows from the Georgian, Victorian and Edwardian periods would have been single glazed.
Double glazing involves having a gap between two panes of glass, which is normally filled with either argon or krypton gas. Both argon and krypton are poor heat conductors, meaning that heat loss is reduced so your home retains the warmth.
At The Sash Window Workshop, the internal glass pane in our standard double glazed units is manufactured using a soft coat low emission glass, which reflects heat back into the building. This helps further improve the thermal efficiency of your home.
Providing planning permission allows it, there is no reason why any replacement timber windows cannot be double glazed. This means that you can benefit from improved thermal efficiency, while also preserving the traditional look and feel of your period property by installing replacement, double glazed, traditional timber sash windows.
All our replacement timber windows are bespoke and designed to enhance both the look and value of your property, by being as energy efficient as possible while also being in keeping with the architectural style of your home.
